[Uml-user] Problems changing methods signatures

[Andre Costa]

Hi Sebastian,

I have a simple case where the problems I mentioned show up. I will try
to describe the steps to reproduce them:

SCENARIO 1
1. create a new diagram
2. create a new class AAA
3. right click on the class name on the "UML Diagrams" panel on the left
4. create a new operation op1() : void
5. edit its properties and try to change its return type to bool. This
yields the following error message:

"An operation with that signature already exists in AAA. Choose a
different name or parameter list."

5.1 only way out is pressing Cancel, and method signature remains
unchanged

SCENARIO 2
(repeat steps 1-4 above)
1. try to add a parameter

The same error msg appears. However, this time clicking on Cancel _does
change the method signature, creating the new parameter_.

I can provide you screenshots for each step above if you believe it will
help you.

HTH,

Andre
